Range extension of Relicina subabstrusa (Parmeliaceae, lichenized Ascomycota) in Argentina and its distribution pattern in the Neotropics

Relicina subabstrusa is known from a few scattered records in the Neotropics. This species lacks any propagules and has a black lower surface and coronate apothecia. This paper extends the known distributional range of R. subabstrusa in Argentina and maps its geographic distribution in the Neotropics. Notes on similar taxa and an updated key for the identification of the Neotropical species of the genus are provided
